Abstract

PCT No. PCT/EP87/00459 Sec. 371 Date Jun. 21, 1988 Sec. 102(e) Date Jun. 21, 1988 PCT Filed Aug. 18, 1987 PCT Pub. No. WO88/01228 PCT Pub. Date Feb. 25, 1988.A spreadable ring for sealing an envelope at the bead of the tire to be retreaded during the pressure and heat treatment in an autoclave. The ring is spread with the aid of cut-outs (a lap joint) or by forming the ends on both sides of the opened section into a tongue-in-groove joint. In both cases a joint is generated which runs in the circumferential direction. Depending on the bead shape the sealing surface is cylindrical or tapered whereby lateral end stops or rims facilitate the positioning. The spreading is accomplished manually by the inherent tensioning force of the ring or with the aid of tensioning cylinders.
